Dyne Pens – Dyne Testing 38 Pen Set
The 38 dynes/cm test pen is a quick method of determining pretreated surfaces. The test pen is used as any other felt tip pen. If the line drawn on the surface to be tested is continuous, the material has been pretreated at no less than 38 dynes/cm and can be printed. If the line is interrupted, the surface has been poorly treated or not treated at all.
Test pens are available in packs of 10 (Part #53410-03).
